I saw a friend's plant or flowers or some shtuff in fish rocks in water in a vase . So I put a plant in clay pebbles to try it out without an airstone ... I was wandering if anyone else used this method before ? I was thinking of doing this with a small fishtank and adding a water filter that will at least CYCLE the water but without a filter to prevent issues with nutrients being messed up ... Probably going to use a carbon stone water filter pump so I don't have to put the carbon rocks in it to cycle .. Need input please ?
